Updated and now navigation is broken

I recently upgraded to Comic Easel v1.8.4.

Before the upgrade my chapters in the navigation dropdown showed with the newest chapters on top (25,24,23,etc). Now it displays (1,2,3,etc).

Also when you select a chapter it jumps the last page of that chapter.

Is there a way to fix this? Can I install v1.8.3 to fix it? If so, where can I download it?

Any help would be appreciated.
